 Jan 24, 2012 Inequality by: Staff Question: by Katie Lunceford (Clinton, MS) 70+30<=100 Answer: 70 + 30 <= 100 True. Logical operators such as the <= symbol are used for comparison purposes. The expression x + 30 <= 100 is true as long as the sum of the two numbers on the left side of the inequality is less than or equal to the number on the right side of the inequality. The following four inequalities are all true: 70 + 30 <= 100 70 + 20 <= 100 70 + 10 <= 100 70 + 0 <= 100 These inequalities can also be written using the ≤ symbol: 70 + 30 ≤ 100 70 + 20 ≤ 100 70 + 10 ≤ 100 70 + 0 ≤ 100 To type the ≤ symbol on a standard keyboard, hold down the right Alt key while you press 8804 on the numeric keypad. After pressing 8804, release the Alt key. (The Num Lock on your keyboard must be turned on for this work. In addition, you must use the numeric key pad on your keyboard to type the alt code. The number keys across the top of the keyboard will not work.) Thanks for writing. Staff www.solving-math-problems.com
